AOT build error after removing @angular/http package

Angular: 5.0.2
ng2-smart-table: 1.2.2

I removed the deprecated [angular/http](https://angular.io/api/http/HttpModule) package from my project, but it seems like this library depends on it.

Output error after _ng build --aot_:
```
ERROR in Error: Error encountered resolving symbol values statically. Could not resolve @angular/http relative to C:/.../node_modules/ng2-completer/ng2-completer.module.d.ts., resolving symbol Ng2CompleterModule in C:/.../node_modules/ng2-completer/ng2-completer.m

```

Could you remove this dependency?
